    摘要： A reduced size and power dot matrix printing head having a chair shaped yoke with opposed off-set portions. Electromagnets are secured to the inner sides of the opposed off-set portions of the yoke permitting staggering of the electromagnets. Heavy biasing springs for securing the print pins in an inoperative position are avoided reducing the size and power of the electromagnets needed resulting in a further reduction in the overall size and power of the dot matrix printing head.

    摘要： Provided is a medical image diagnosis apparatus which requires a small area for installation, has a short length in an axial direction of the apparatus, can reduce a problem of the strength of a top plate, and can simultaneously carry out dynamic PET-imaging of the entire body. A top plate (61) on which an examinee lies is moved through a tunnel of a CT gantry (2) and a PET gantry (3) to execute CT imaging and PET imaging. A PET unit consisting of a plurality (e.g. seven) of PET units (32) has a length of 2 m in the axis direction, the visual field thereof covers the whole body and the whole body can be simultaneously subjected to dynamic PET-imaging. For the maintenance of the PET gantry (3), the diagnosis apparatus is separated at an arbitrary PET unit (32) to be maintained, the apparatus slides on a rail (31) in the axis direction and is separated for maintenance operation. Accordingly, a large space for maintenance is not required and the area for installation is small.

    摘要： This invention has one object is to provide radiation tomography apparatus that allows production with low price through suppression in number of radiation detectors to be mounted. One of the detector rings in this invention is a first detector ring having a sufficient internal diameter to introduce shoulders of the subject M, and the other is a second detector ring having a smaller internal diameter than the first detector ring. In so doing, the radiation detectors forming the detector ring may be suppressed in number, which may provide radiation tomography apparatus of low price. Moreover, a smaller diameter of the detector ring may result in improved spatial resolution and detection sensitivity of radiation.

    摘要： One purpose of this invention is to provide radiation tomography apparatus with easier maintenance. A specific approach for this purpose is as follows. That is, a detector ring in the radiation tomography apparatus includes two or more rings. Moreover, a ring moves as to approach a next ring, whereby both the rings are connected. If radiation tomography is conducted while a clearance is provided between the rings, detection sensitivity of the detector ring decreases due to the clearance. On the other hand, according to this invention, the ring moves as to approach the next ring, which results in a narrower clearance. Accordingly, radiation that is not observed may be reduced as much as possible.

    摘要： This invention has one object to provide radiation tomography apparatus that allows suppression of arithmetic load of detection data with a wider detector ring. In order to achieve this purpose, the radiation tomography apparatus according to this invention performs coincidence only when two scintillation counter crystals that detect gamma rays coincidentally (A) belong to the same ring unit, or (B) belong to each of the ring units adjacent to each other. Accordingly, a distance in the central axis direction between the radiation detecting elements is limited to be equal to or less than a thickness of the ring unit in the central axis direction. Accordingly, radiation tomography apparatus may be provided that allows generation of the sectional image suitable for diagnosis while arithmetic load is suppressed.

    摘要翻译： 本发明的一个目的是提供一种放射线断层摄影装置，其能够利用较宽的检测器环来抑制检测数据的算术负载。 为了达到这个目的，根据本发明的放射线断层摄影装置只有当两个同时检测伽马射线（A）的两个闪烁计数晶体属于相同的环单元时，或（B）属于相邻的每个环形单元 对彼此。 因此，辐射检测元件之间的中心轴方向的距离被限制为等于或小于环形单元在中心轴线方向上的厚度。 因此，可以提供放射线断层摄影装置，其允许在抑制运算负载的同时产生适于诊断的截面图像。

    摘要： A grinder includes a housing, a gear cover attached to the housing by a plurality of screws, a spindle case attached to the gear cover, a wheel guard rotatably mounted on the spindle case for covering approximately a half of a disc-shaped tool bit attached to a spindle, a stop piece that regulates the rotation of the wheel guard. The wheel guard is selectively fixed to and unfixed from the spindle case. The stop piece is fixed to the housing together with the gear cover by at least one of the plurality of screws. The stop piece has an abutting section at which the stop piece abuts the wheel guard to regulate the rotation of the wheel guard. The abutting section is located at a position deviated from an axial line of the at least one of the plurality of screws.
